Like all species of Jorunna, the mantle is covered with spiculate papillae called caryophyllidia. The background colour ranges from cream to pale yellow and scattered over the foot and the mantle are brown to black spots and patches of irregular shape and size. On the mantle the spots are formed by aggregations of black or brown caryophyllidia. There is a distinctive large spot on the posterior tip of the foot. The gills are dark brown or black, as are the rhinophore clubs.

This species is very similar in colour to the Japanese J. parva and the widespread Indo-West Pacific unnamed 'species' Jorunna sp.2. However, it is reported to grow to 60mm in length, which is about three times the length of J. parva and Jorunna sp. 2.
